Best way to run games from flash drive?

[Maxaxle]

I'm totally fed up with trying to run games from my computer's hard drive, but I have an 8GB flash drive now and I'm not really sure how to set it up for OPL. The PS2 recognizes it, I think, because I set up the following folders on the flash drive:
[root]:\PS2SMB\CFG
[root]:\PS2SMB\CD <-contains 1 ISO file, CD format
[root]:\PS2SMB\DVD <-contains 1 ISO file, DVD format
[root]:\PS2SMB\VMC
And after removing it after attempting to read it with OPL, an empty folder was placed at the root of the flash drive: VMC. So I know I'm on to something, but I'm not really sure how to set up the flash drive's file structure.

The guides at http://openps2loader.info/8/ are down, but I'm 99% sure you just need to move all your folders up one level.

e.g.

[root]:\CD
[root]:\DVD
etc.

Make sure it's formatted as FAT32 and you defrag it after your games are in place.

Done, and done. But do the .iso files have to be named after the games (as in, what the PS2 refers to them as), or can you name them anything?

EDIT: Hooray, my USB and ethernet folders are finally showing up, HOWEVER nothing shows up in them. Is .iso the format to be using? Are there any other files I need to put in the folders?

Here, on SKS the FAQ is on....

OPL Guide

Scroll a bit down were it stays "*NEW* Version 0.8 supports using the .iso format..."

There you can read how you have to name your images....

Great, thanks!

At some point you might try to copy a file to your USB device and end up with a "not enough space" error message, even though it says there is enough space free. It's actually caused by the FAT32 file size limit, which is restricted to files < 4.0 GB.

In those cases you need to split the files up using ul_install, as described in the guide LopoTRI linked above. On the Wii you'd use the WBFS container instead.

(Even though I don't use USB mode for PS2, I still run into this problem a few times per year when moving other data around and it invariably confuses me for a few minutes.)

ul_install is run through command prompt. No love for it, so I use GUI software like USBUtil 2.0 for this purpose instead.
